(embodiment 8)
Fig. 8 represents the automobile-use suspension arm (the utility model example 8 of above-mentioned table 1) of embodiment 8 of the present utility model, (a) is birds-eye view, is (b) the AA cutaway view of arm, is (c) the BB cutaway view of arm.In the present embodiment, to based on marking identical symbol and omit detailed explanation with the part of embodiment 1 essentially identical technological thought, different piece is described in detail.
As shown in Fig. 8 (b), (c), the utility model example 8 shape of falling U cross section structure for the cross sectional shape of the arm 7 in utility model example 1 (with reference to Fig. 1) turned upside down., web 6 is arranged on the structure of the other end separately (position topmost) on the above-below direction of rib 5a, 5b, 5c.This situation is equivalent to the situation that transverse axis (H-Hr)/Hr is 0.05 shown in Fig. 2 (a).In this situation (situation of the utility model example 8), as Tr/W=0.17,0.13 time, f/f
0become respectively 1.21,1.3, with respect to comparative example, eigentone once can improve approximately more than 20%.; if meet 0.05≤(H-Hr)/Hr≤0.25 shown in above-mentioned formula (1); as shown in ◎ mark in above-mentioned table 1, just reached the expected value (f/f of intensity with respect to the input of the vehicle fore-and-aft direction rigidity abundance degree high (having guaranteed out-of-plane bending rigidity) of the arm 7 of face moment of face { particularly with respect to }, regulation
0=1.14)., explanation can make the eigentone of low order (for example, once) improve.And, if take the cross sectional shape (with reference to Fig. 8) as the arm 7 of the utility model example 8, as shown in △ mark in above-mentioned table 1, also than being easier to realize the manufacture that utilizes forging.And the cross sectional shape being made as the arm 7 of the utility model example 8 can make rainwater, mud be difficult to accumulate, and is therefore more preferably.
It should be noted that, in present embodiment 1～8, the situation that the total length L of the length direction at whole arm 7 is provided with to the cross sectional shape of above-mentioned regulation is illustrated, but may not be defined in this, at least between L/4 to the 3 × L/4 the length direction from one end, be provided with the cross sectional shape of described regulation at arm 7.
In addition, in present embodiment 1～8, to the height H of rib 5a and rib 5b respectively identical, rib 5a and rib 5c height H respectively identical situation be illustrated, but may not be defined in this.,, as long as meet the specific project of recording in the related utility model of the application's technical scheme 1, the height H of rib 5a and rib 5b also can be different so.Equally, as long as meet the specific project of recording in the related utility model of the application's technical scheme 1, the height H of rib 5a and rib 5c also can be different so.
In addition, by the cross sectional shape of described regulation is set between L/4 to the 3 × L/4 on the length direction from one end of arm 7, and make from one end of arm 7 and the other end point to be clipped to L/4 length direction and meet (H-Hr)/Hr=1 (with interior part with the orthogonal cross sectional shape of length direction, be made as H shape cross section structure), can realize thus and possess opposite moment of resistance and face moment of face both have the automobile-use suspension arm of the arm 7 of advantage.
In the automobile-use suspension arm forming by aluminum alloy forged of the present utility model, need to ensure that the aluminum alloy using is taking the high corrosion-resistants such as desired high strength, anticorrosion stress-resistant cracking behavior and even durability as prerequisite.Therefore,, in aluminum alloy, preferably formed by 6000 line aluminium alloys that specify in JIS or AA.This 6000 is that the specific chemical composition composition of Al alloy is set to, make essential element contain Si:0.8～1.3%, Mg:0.70～1.3% according to quality %, add as required on this basis Cu, Zn, Fe, Mn, Cr, Zr, Ti etc., all the other are made up of Al and inevitable impurity.
Aluminum alloy forged (automobile-use suspension arm) of this composition is same with the suspension arm of H shape cross sectional shape up to now, can manufacture by common method.This is also advantage of the present utility model.That is, the aluminium alloy cast ingot with above-mentioned composition is being homogenized after heat treatment, the Forging Parts of the shape of the each embodiment to described arm uses the forge hot processing of mould and can manufacture at an easy rate, also can realize batch manufacturing.Then, this Forging Parts is implemented to solution treatment and Quenching Treatment, artificial aging processing afterwards etc. modified, and realize desired intensity (yield strength).
Industrial applicibility
According to the utility model, can provide and adopt light weight and cheap structure, and guarantee the intensity (particularly out-of-plane bending rigidity) with respect to the input of vehicle fore-and-aft direction, and the automobile-use suspension arm that the eigentone of low order is improved.Therefore, be applicable to further requiring the suspension arm etc. of weight-saving self-propelled vehicle.
